  1. A crime scene is taped off as a rectangle 18 feet long and 12 feet wide. What is the total length of tape needed to go around the perimeter?

    Answer: 60 feet

    Perimeter of a rectangle = 2(length + width) = 2(18 + 12) = 60 feet.

  2. An officer measures a square evidence grid that is 9 feet on each side. What is the area of the grid?

    Answer: 81 square feet

    Area of a square = side × side = 9 × 9 = 81 square feet.

  3. A parking lot is 50 feet by 40 feet. How many square feet of surface must be searched?

    Answer: 2,000 square feet

    Area = length × width = 50 × 40 = 2,000 square feet.

  4. A triangular plot at an intersection has a base of 20 feet and a height of 15 feet. What is its area?

    Answer: 150 square feet

    Area of a triangle = ½ × base × height = ½ × 20 × 15 = 150 square feet.

  5. A holding cell measures 12 feet by 10 feet. What is its perimeter?

    Answer: 44 feet

    Perimeter = 2(12 + 10) = 44 feet.

  6. A circular search area has a radius of 7 feet. Using 3.14 for pi, what is its approximate area?

    Answer: 153.86 square feet

    Area of a circle = pi × r² = 3.14 × 7 × 7 = 153.86 square feet.

  7. An officer must fence a rectangular yard 25 feet long and 15 feet wide. How many feet of fencing are required?

    Answer: 80 feet
